The travel and leisure industry comprises several different industries that make up its groundwork. These sub-industries include modes of transportation, vacation destinations, lodging options, and companies that offer various forms of recreation and leisure. The travel and leisure industry is supported by the priority that the general public places upon taking annual vacations for the purposes of relaxation or education.
Overall, the travel and leisure industry is composed of four main sectors: entertainment, recreation, tourism, and travel.

Entertainment consists of any activity that provides the general public with pleasure during their leisure time. These activities may include watching television, attending a theatrical or performance or the opera, going to the movies, attending a sporting event, and playing a variety of board games or video games. Recreational activities are intended specifically for the therapy provided for the physical, mental, and emotional states of the mind and body. The most usual recreational activities include writing, art, yoga, trips to amusements parks, or attending restaurants, but new sectors such as adventure tourism, motor sports, and extreme events such as bungee jumping or sky diving have emerged in this realm as well. The tourism sector consists of travel and tour agencies used by the public to book trips and vacations, and as such ties in neatly with the travel sector of travel and leisure. There are many different forms of travel for those partaking in trips and vacations, including air and sea travel as well as on land. Cruises are popular for the travel and leisure industry, as are a variety of destination resorts worldwide.
